PART I
1. Access the site census bureau, data tools, quickfacts, or type in URL
• Select the State of Utah. In the pull down menu for City, choose either Salt Lake City or Draper, then click Search and fill out chart below.
• Under the People Quickfacts, find the female persons percentage of the population; calculate how many people in this population are women. Men?
|a. Total Population __________ |Percent Women ___________ |Total Women ___________ |
| |Percent Men ___________ |Total Men ___________ |
b. Is it a reasonable assumption to estimate that about half of your populations are men and half are women? Explain why.
c. We will also estimate that about half of the population in each age group are men and half are women. Is this a reasonable assumption? If not, for which age groups would this assumption probably not be true? Explain why.
PART II
Task 2: Choose two countries (one from List A and one from List B)
Make a handout about the population of each country in 2009. Each country must have a pyramid, explanation of the pyramid, and compare/contrast section.
Access the site .
• Click DATA tab.
• Choose International Database.
Now you are in the International Database. Click on Select Report and use the pull down menu to select Population pyramid graph. Then choose the Year and Country from the appropriate pull down menus.
• For each pyramid: Right click each pyramid and select Copy Image. Put the image in a new Microsoft WORD file, by right clicking and choosing paste. Properly label for each country with the year.
• Explain what factors might have affected the population and what cohorts seem to be dominant/dwindling. Save your your document.
• You may want to find out some other information about these countries to give good explanations why these age-structure pyramids differ (such as the chart under the demographic indicators tab). Also, CIA World Factbook website has useful information.
PART III – Choose either 3a or 3b
Task 3a: Create a presentation about one country for two different years, preferably at least 50 years apart (or as far apart as data is available). Be sure to explain the pyramid and provide some reasoning why it has changed over the years. You should make population projections for the future using the Pert formula.
Task 3b: Create a presentation about two countries for the same recent year, each country should have different population pyramid graphs. Be sure to explain the pyramids and provide some reasoning why they are different. You should make population projections for the future of each country using the Pert formula.
Every group will hand in one Age Structure Worksheet and present their findings in a prezi or poster format.
Remember:
• Every person in your group should give feedback and offer comments since you will be graded as a team
• Use what you already know about demographic transitions! Use vocabulary words, refer to specific areas of your pyramid, and properly cite your other sources.
Pt (population at time t)= Po( initial population)er t (growth rate x time)
